'6 Claims.

This invention relates to building constructions, and has reference more particularly to means for attaching nailing strips to wall panels, tiles, etc.

In the construction of walls and ceilings, it is common practice to attach grounds or nailing strips to walls of gypsum board, gypsum tile or plaster on expanded metal lath, by prmching holes through the wall panel and then passing an attaching wire through the holes and around the nailing strip or ground strip, the ends of the wires being twisted together securely. This operation is troublesome and requires an excessive amount of labor in erection.

An object of this invention, therefore, is to provide a clip or other suitable means for conveniently attaching grounds or nailing strips to a wall or ceiling panel; also to improve building constructions in other respects hereinafter specified and claimed.

Reference is to be had to the accompanying drawing forming a part of this specification, in which Fig. 1 is a perspective sectional view through a wall construction employing my improved attaching clip,

Fig. 2 is a sectional elevation on a large scale showing the method of applying the attaching clip,

Fig. 3 is a perspective view of one of the attaching clips,

Fig. 4 is a perspective sectional view showing the attaching clip applied to a tile wall,

Fig. 5 is a fragmentary elevation of the attaching clip applied to an expanded metal lath and plaster wall,

Fig. 6 is a perspective view of a modified form of attaching clip, and

Fig. 7 is a sectional, perspective view showing the clip of Fig. 6 applied to a tile wall.

Walls and ceilings are commonly formed of plaster boards 10, which consist of a core material 11 largely of gypsum or other cementitious material, and heavy paper cover sheets 12 and 13 on the faces of the core 11. In applying my improved attaching clip for attaching a ground or nailing strip 14 to the front face of the board 10, I punch or drill a hole 15 through the board at a point located near the edge of the nailing strip 14.

After the hole 15 is formed in the board 10, my improved attaching clip 16 is utilized to connect the nailing strip 14 to the board 10. This attaching clip has an outstanding leg 17 extending substantially at right angles to the clip 16,

and the leg 17 is then bent backward upon itself to form a resiliently and integrally mounted pressure flange or leg 18, which preferably extends at a slight angle to the leg 17 and is adapted to press upon the exposed face of the rear paper cover sheet 13 of the board 10. The end of the clip 16 opposite the leg 17 is formed into a right angle leg 19 which extends in a direction opposite to that of leg 17. A prong 20 is formed on the end of leg 19 and extends substantially parallel to the clip 16, being adapted tobe driven into the nailing strip 14 by a hammer. It will be observed from an inspection of Fig. 2, that the clip 16 with the two outstanding legs 17 and 19 is substantially Z shaped. Ihe legs 17 and 18 of the clip are first inserted through the punched hole 15, then by a simple angular movement of the clip, the-leg 18 presses resiliently against the .paper cover sheet 13 as the prong 26 is driven into the nailing strip 14 so that said nailing strip is held snugly and resiliently against the front of the board 10.

The attaching clips may be also applied to clay tile 21, (Fig. 4) or expanded metal lath 22 (Fig. 5) having a plaster coating 23, as seen in Fig. 5, by simply punching the hole 15 through the wall panel in the desired location. Tiles 24 (Fig. 7) of gypsum or other cementitious materials, are often formed with cylindrical core holes 25 with a considerable body of material between the core holes and the surface of the tile. For such a construction, it is preferable to punch or drill a hole 26 in the face of the tile, and this hole may or may not pass into the core hole 25, depending upon its location. A modified form of clip 2'7 is utilized for this construction, one end of the clip 27 being provided with an outstanding prong 23 extending at an obtuse angle to the clip body 27. By an angular movement, the prong 28 and clip 27 is pushed down into the hole 26 and then the prong 28 digs into the side wall of the hole 26 and firmly anchors the clip to the tile 24. A prong 29 formed on the end of a clip leg 30, is then'driven into the nailing strip 14 in the manner as hereinabove described.

The attaching clips are preferably made of spring steel, which may be tinned or galvanized to prevent rusting. They may also be formed of other materials if desired, such as spring bronze, brass, as well as suitable non-metallic materials. After attaching the nailing strips 14 to the face of the wall or ceiling panel, baseboard 31, moldings or other objects may be attached to said nailing strips in the usual manner by nails or screws. A plaster coating 32 may be also applied to the outer surface of the board 10 or other wall panels, said plaster coating extending into contact with each edge of the nailing strip 14 so as to embed the clip 16 and firmly anchor the clip and nailing strip in position, and to also cover up the hole 15. If the boards 10 are to be resiliently attached to steel studs 33, spring clips 34 may be provided for attaching at one end to the studs 33 and at the other'end being provided with outstanding fingers 35, providing opposed channels for the reception of the abutting edges of the gypsum boards 10. The bottoms of the steel studs 33 and the bottoms of the boards 10 may be received in a base strip 36 having upstanding, in-

tegral fingers 3'7.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. An attaching clip for nailing strips, a clip body having an outstanding leg adapted to be inserted through an opening in a wall panel and having a resilient section adapted to resiliently engage the rear face of said wall panel, and means associated with said clip body for engaging a nailing strip and holding said nailing strip into contact with the front face of the panel.

2. An attaching clip comprising a body portion adapted to extend through an opening in a building panel, an outstanding leg formed on the inside end of said body portion, a panel engaging leg integrally connected to said outstanding leg and having a resilient section adapted to engage the rear face of said panel, and means'associated with the opposite end of said body portion for engaging a nailing strip and holding said nailing strip into contact with the front face of said panel. l I

3. In a building construction, a building panel, a nailing strip in contact with one face of said the rear face of said building panel, and means associated with the opposite end of said clip for engaging said nailing strip and securing said strip firmly in contact with the front face of said building panel.

4. In a building construction, a building panel having an opening formed'therein, an attaching clip extending through said opening and having means associated with its inner end for engaging the rear face of said panel, a nailing strip engaging the front face of said panel, means associated with the opposite end of said clip for engaging said nailing strip and holding the latter in position, and a plaster coating on the front face of said panel embedding said clip and covering saidopening.

5. In a building construction, expanded metal lath and'plaster forming a wall panel, a nailing strip raised to contact with the face of said panel, an attaching clip extending through an opening in said metallath and through said plaster layer, and means associated with said attaching clip for engaging the rear face of said panel and for engaging said nailing strip to hold said nailing strip in close contact with the front face of said panel.

6. In a building construction, a cementitious tile having an opening formed in the face thereof, a nailing strip in contact with the face of said tile, an attaching clip having means for engaging said nailing strip, and a prong formed on said clip and extending into said opening to anchor said clip to said tile.
